GAS-GENERATOR.

Speccaton of Letters Patent.

Patented March 5, 1907.

Application filed February 21,1906. Serial No. 302.289.

To all whom, t may concern,.-

Be it known that I, CLARENCE D. FINLEY, a citizen of the United States, residing at Memphis, inthe county of Shelby and State of Tennessee, have invented a new and useful Gas-Generator, of which the following is a speciiication.

The present invention relates to an apparatus for the manufacture of gas for illuminating and heating purposes.

The principal object of the invention is to provide a Cheap and simple form of gas-generator which may be used for small plants, such as for domestic purposes, wherein gasolene or other light hydrocarbon is vola tilized by the action of heat and conducted directly to the burners.

A further object of the invention is to provide a device of this character in which provision is4 made for entirely surrounding the gasolene containing casing with a waterjacket, the water-jacket being heated enternally and the heat conveyed to the gasolenetank through the water.

A still further object of the invention is to provide a device of this character in which the water-jacket is surrounded by an eXternal casing for conserving the heat and exposing the greater portion of the outer surface of the water-jacket to the action of theprod- Iucts of combustion.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in the novel construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacricing any of the advantages of the invention.

In the accompanying drawings there is shown in sectional elevation a gas-generating apparatus constructed in accordance with the invention.

The central tank 1 is preferably cylindrical in form andvhas a conoidal top, from the upper end of which leads a gas-outlet 2, and

said tank is provided with a filling-pipe 3,

through which the liquid gasolene or other hydrocarbon may be introduced, the top of said pipe being closed by a removable cap 4.

The gasolene-tank is entirely surrounded by a water-j acket 5, into which water may be admitted through a supply-pipe 6, the Water being maintained at the level indicated by means of a float-valve 7 of any ordinary construction, and at a point above the Waterline the jacket is provided with a petcock 8, through which the steam may be discharged from time to time in order to avoid danger of explosion.

Surrounding the water-j acket to a point at least up to the waterline is a heat-conserving casing or j acket 9, the lower central portion of which has an opening l0, which maybe placed directly above the lamp or gas-j et for the purpose of heating the water in the jacket 5.

As a matter of convenience the outer jacket is provided with standards 11, and the heating device in the present instance is shown as comprising a burner l2 ,that is connected to the gas-outlet pipe 2, so that the apparatus is kept in operation by its ovvn gas. When starting, it will of course be necessary touse some separate source of heat.

In the operation of the device the heat of the outer jacket 5 is absorbed by the water and conducted to the gasolene-tank l, the temperature being suiciently high to volatilize the gasolene or other light hydrocarbon. The vapor is driven off through the pipe 2 to the point of consumption, but no air is mingled with the gas or vapor until the burner is reached, so that danger of explosion at the generating-tank is reduced to a minimum.

Having thus described the invention, what is claimed is A domestic gas-generator comprising a pair of closed chambers, each having a conoidal top, and one being entirely inclosed within the other and having its walls spaced at substantially equal distances from the other at all points, the innermost chamber serving for the reception of hydrocarbon, a hydrocarbon-inlet, and a gas-outlet connected to the top of the inner chamber, the outer chamber serving as a water-jacket and the upper portion thereof forming a steamspace, a secondary jacket or casing Surrounding the water-space of the outer chamber and having a closed top, and means for main- IOO taining the Water-level of the outer chamber In testimony that I claim the foregoing as in approximately the horizontal plane of the my own I have hereto aiiixed my signature in closed top of the outer jacket, the bottom of the presence of tWo Witnesses.

said outer jacket being provided With an CLARENCE D. FINLEY. opening for the admission of a heating me- Witnesses: dium, and supporting-legs on which said outer i J. W. STOTTS,

jacket is mountedq E. F. STAPLETON.
